A duckbill check valve is a one-way valve that prevents backflow. They need no intervention to open and close and are particularly useful in applications that involve abrasives. This article describes some of the most important characteristics of this type of valve. It also discusses the advantages of using this type of valve.
Duckbill check valves are a one-way valve
A duckbill check valve is a special one-way valve with flow-sensitive, variable-area flaps. Its name is derived from the shape of the valve’s flaps. In zero-flow conditions, these flaps remain closed, but as the flow increases, pressure on the flaps increase. This causes the valve to open.
They prevent reverse flow
A duckbill check valve is a type of valve that prevents reverse flow through a flexible tube. Its name comes from its flattened end, which opens when pressure is applied to the inlet side. Once the pressure is removed, the valve returns to its flattened state and cuts off the flow.
They require no intervention to open or close
Duckbill check valves are designed to operate with minimum intervention and are easy to install. Their patented Curved Bill provides tight sealing and backflow prevention. The patented curvature of the bill prevents the valve from cracking under high pressure, eliminating standing water and maximizing the storage volume of upstream pipes.
They are suited for applications involving abrasives
Duckbill check valves are ideal for applications that require flow control and contain abrasives. These valves have elastomeric constructions and can be fitted with visit this page different types of end connections. They are designed to withstand continuous exposure to abrasives and chemicals and provide reliable performance.
They achieve a tight seal
Duckbill check valves achieve a close, tight seal by flexing when pressure varies in the inlet or outlet. Their structure and design allow them to be easily incorporated into a variety of applications. They are rust-free and low-maintenance, making them an ideal choice for many applications. They are also highly durable and versatile.
They are easy to install
A duckbill check valve is a type of surge relief valve. Its design allows it to flex to accommodate pressure spikes and water hammer. Duckbill check valves are manufactured by companies like Emerson Process Management and Daniel Measurement and Control Inc.
